“…In turn, the abundance of the individuals of smaller sizes of M. palmata can be positively correlated with macroalgae in reef's surfaces (Bazterrica et al, 2020). The presence of more refuge inside macroalgae may also explain these results (see Morales-Núñez and Chigbu, 2019) and could also be significant for L. acuta since its abundance also increases under areas covered by mimics of macroalgae. In turn, on the surface, macroalgae might act as a barrier to grazing as the lowest density of Heleobia spp.…”

“…Freshwater inflow directly into the MCBs is higher in the northern bays because of the location of the St. Martin River. Phytoplankton biomass, macroalgae abundance and the associated amphipods, as well as fish abundance, are higher in the northern than southern bays [13,26,27]. Groundwater is the main pathway through which freshwater and nutrients enter the system, while winds and tidal exchange at the Ocean City and Chincoteague inlets regulate the system [23].…”

Carbon (δ13C) and nitrogen (δ15N) isotopes were used to evaluate spatial, temporal, and interspecific differences in trophic relationships of four fish species (Paralichthys dentatus, Anchoa mitchilli, Leiostomus xanthurus, and Bairdiella chrysoura) in Maryland’s coastal bays. The δ13C values for all species were more enriched in 2017 than in 2018, a year of higher-than-average rainfall that likely caused higher amounts of terrestrial carbon to enter the estuary. There were significant differences among species in the δ13C values, with L. xanthurus being the least depleted (−17.2‰ in 2017; −18.8‰ in 2018). Spatially, the δ13C values of the species, particularly P. dentatus and B. chrysoura, were more depleted in the northern bays, which have a higher nutrient content and receive more freshwater inflow directly from tributaries, than the southern bays. The observed δ13C values (−19.5 ± 0.2‰ to –17.2 ± 0.3‰), however, indicate that marine phytoplankton was the primary carbon source of the fishes. Overall, A. mitchilli was the most enriched in δ15N (13.0‰), and L. xanthurus was the most depleted (10.2‰). δ15N was more enriched in fish from the more human-impacted northern bays than in fish from the southern bays, though this might also have stemmed from the differences in the diet composition of the species in the northern and southern bays. A. mitchilli had the highest trophic level, while L. xanthurus and P. dentatus had the lowest trophic levels. Niche breadth was widest in L. xanthurus compared to the other fish species, suggesting a higher variability in diets among L. xanthurus individuals, leading to specialized diets. There was a high niche overlap between B. chrysoura, A. mitchilli, and L. xanthurus, which indicates they fed on similar prey resources.
